I love the way Stanley doesn't even seem impressed by the result - just another ordinary sub-1:15 4BLD solve. (Even if it is his first ever in competition.)

Stanley (or anyone else who knows), where did you get the blindfold? I want to learn to do the nod-don thing. :)

Edit: One more comment - this video shows that, with the nod-don, we need judges who are very knowledgeable about BLD solving now, and they need to be paying VERY close attention during the memorization phase. Stanley clearly did not make any moves here prior to the blindfold being in place - the video shows that clearly - but he started making moves just milliseconds after the blindfold went on. Judges will need to be watching for the nod-don and verifying that no moves are applied until the blindfold is in place.

IMHO, nod-don should be disallowed for exactly this reason. It's too difficult to judge, and we already have enough problems with inexperienced or inattentive judges.

Unless nod-don is questionable (as in there are moves done before turning) it should be fine. Who says how you have to put the blindfold on? If something is different, that doesn't make it bad, unless it's explicitly against the regs.

First off, Congratulations Stanley on re-getting the 4x4 BLD WR single and with such a great time. Well done and keep the hard work up. I look forward to seeing a sub 1 4x4 BLD single soon;)

I would have to agree with you both in that the nod-don should be illegal, especially since there is a (well will be a higher change if this goes on) that the blindfold is not fully on once the first moves are applied. I am not saying that this is at all what Stanley was/is doing, but I am referring to if other people start to to do it, and try the nod don, then some (and I hope that none do it, but there is a chance) that people will try the nod don and do a few moves before the judge puts an object in front of the competitor.

And as it has already been stated, doing the nod don would require the judge(s) to be very fast at placing something in front of the competitor, but if the judge is caught off guard for even a second, moves can be applied with the blindfold not fully down.

The WCA regulations have it very clear that something should be between the cube and competitor during the solve, and that even if (hypothetically) something is not between the cube and competitor then the blindfold should be down all the way that the competitor can not see the cube at all (B4c1). And just so all can see, here is the words from the regulations page;
B4) Blindfolded phase:
  • B4a) The competitor dons the blindfold to start the blindfolded phase.
  • B4b) The competitor must not apply moves to the puzzle before they have fully donned the blindfold. Penalty: disqualification of the attempt (DNF).
  • B4c) The judge must ensure that there is an opaque object between the competitor's face and the puzzle while the competitor is solving.
    • B4c1) In all cases, the competitor must wear the blindfold such that their view of the puzzle would still clearly be blocked if the opaque object were not in the way.
    • B4c2) By default, the judge should place the object (e.g. a sheet of paper or cardboard) between the competitor and the puzzle while the competitor is wearing the blindfold.
Edit: I just watched Jack's 3x3 BLD single and realized that the same nod don applied to his solve as well. I (again) do not think that the experienced solvers like Stanley and Jack are doing the nod don to get any sort of advantage, but I am saying what I say because lesser experenced solvers might try to immitate Jack, Stanley etc. and try to get a slight advantage in doing the nod don.

I think it's pretty clear that the nod-don examples we've been talking about here do not violate any current rules. The concern is obviously the potential that some future important solve might be a problem. The current regulations are kind of okay, but they do require very careful behavior on the part of the judge - the judge needs to be watching carefully for the blindfold to be in place before moves are made on the cube, and needs to DNF the solve if not. That's a lot more responsibility than I've seen from judges in a lot of the competitions I've been to (including some where Stanley has been solving).

@ everyone saying that noddon creates an advantage:
the exact same advantage can be gained due to the lack of a sight blocker for the first few turns of execution, which is caused by judge reaction time
eliminating this would be impossible, so there's no reason noddon should be banned for that

Also you could gain the same advantage by doing the first few turns OH so banning noddon doesn't even get rid of the issue, and yeah the sight blocker isn't there anyway.
